In order to achieve the purpose, the utility model provides a pair of powder spreader material conveying mechanism includes cascaded U type casing, the invariable distance transport auger of reducing, U type casing strengthening rib, subtracts heavy awl erection support, subtracts heavy awl and subtracts heavy awl adjusting plate.
The bottom of the stepped U-shaped shell is arc-shaped, the two sides of the stepped U-shaped shell are in the shape of an inclined plane cut in the arc, and the stepped U-shaped shell divides the powder compartment into a front part, a middle part and a rear part 3;
the variable-diameter and non-variable-pitch auger is flatly laid in the circular arc at the bottom of the U-shaped shell, and the distance from the outer edge of the blade of the auger to the bottom of the shell is consistent;
the U-shaped shell reinforcing rib is fixed in the middle of the U-shaped shell and used for keeping the U-shaped shell not deformed in the processing process;
the weight reducing cone mounting support is welded at the bottom of the reinforcing rib of the U-shaped shell and used for fixing the weight reducing cone;
the weight reducing cone adjusting plates are symmetrically arranged on two sides of the weight reducing cone, and the weight reducing cone adjusting plates are provided with adjusting slide holes, so that the length of the weight reducing cone adjusting plates can be adjusted according to the specific gravity and the bonding degree of materials, and the pressure of the materials above the conveying auger is reduced to the maximum extent.
Has the advantages that:
the utility model discloses the effectual powder railway carriage or compartment bottom of having solved has a large amount of powders to remain and piles up and cause the automobile body dead weight to increase, problem that actual powder railway carriage or compartment volume reduces. And the problems that the material level in the powder bin for actual construction cannot be maintained in a good range, and the spreading precision is reduced due to the phenomenon that a material accumulation card in the middle of the powder bin lags behind and lacks materials are solved. In addition, the unique sectional type reducing and distance-invariant conveying auger can effectively reduce the power loss during the cement conveying, and the economic benefit is enhanced.

Detailed Description
The technical solution of the present invention is further illustrated by the accompanying drawings 1-7 and examples.
Referring to fig. 1-7, a powder spreader material transport mechanism 3 is disposed inside the powder spreader 1, specifically, below the powder compartment 2; the material conveying mechanism 3 of the powder spreading vehicle comprises a stepped U-shaped shell 4, a reducing non-variable-pitch conveying auger 5, a U-shaped shell reinforcing rib 6, a weight-reducing cone mounting support 7, a weight-reducing cone 8 and a weight-reducing cone adjusting plate 9.
Referring to fig. 1-7, further, the stepped U-shaped shell 4 is formed by a high-strength manganese steel plate in one step using a platen die, the bottom of the stepped U-shaped shell is designed to be circular arc, the two sides of the stepped U-shaped shell are inclined planes cut from the circular arc, and an included angle between each inclined plane and a horizontal plane is larger than a repose angle of a material to be conveyed, so that residual accumulation of powder in the conveying shell can be effectively reduced;
the stepped U-shaped shell 4 is in full-welding connection with a front end plate 10 of the powder chamber 2 and a rear end plate 11 of the powder chamber 2, and the powder chamber 2 is divided into a front part, a middle part and a rear part 3;
the variable-diameter and non-variable-pitch conveying auger 5 is tiled in the circular arc at the bottom of the stepped U-shaped shell 4, and the distance from the outer edge of an auger blade to the bottom of the shell is consistent; furthermore, the reducing and non-variable-pitch conveying auger 5 is matched with the stepped U-shaped shell to be divided into 3 sections, namely a front section, a middle section and a rear section, the diameter of each section of blade needs to be designed according to the blanking proportion of the front part, the middle part and the rear part of the powder compartment to be 40 percent, 35 percent and 25 percent, so that the materials at the front part, the middle part and the rear part in the powder compartment can basically fall down simultaneously in the construction process, or the front part can be blanked quickly, the middle part is second and the rear part is slowest, and the problems that the material level in the actual construction powder bin cannot be maintained in a good range, the material accumulation card at the middle part of the powder bin lags behind the side starved material, and the spreading precision is reduced are solved effectively. Meanwhile, the unique sectional type reducing and distance-invariant conveying auger can effectively reduce the power loss during the cement conveying, and enhances the economic benefit.
The U-shaped shell reinforcing ribs 6 are fixed in the middle of each section of the U-shaped shell 4 and used for reducing the deformation of the U-shaped shell in the welding process;
the weight reducing cone mounting support 7 is welded at the bottom of the reinforcing rib 6 of the U-shaped shell; furthermore, the fixing hole on the weight reducing cone mounting support 7 adopts a conical wire process;
